Structural analysis of proteoglycan macrophage colony-stimulating factor.

Macrophage Colony-Stimulating Factor

Granulocyte Macrophage Colony-Stimulating Factor

Experimental autoimmune encephalomyelitis (EAE), a model for multiple sclerosis, can be induced by immunization with a number of myelin antigens. In particular, myelin oligodendrocyte glycoprotein, a central nervous system (CNS)-specific antigen expressed on the myelin surface, is able to induce a paralytic MS-like disease with extensive CNS inflammation and demyelination in several strains of ...

Granulocyte-Macrophage Colony-stimulating Factor

We show that 1,25-dihydroxyvitamin D3 (1,25[0H12D3), the most hormonally active metabolite of vitamin 113, modulates sensitively and specifically both the protein and messenger RNA accumulation of the multilineage growth factor granulocyte-macrophage colony-stimulating factor (GM-CSF). The regulation of GMCSF expression is seen in both normal human mitogen-activated T lymphocytes and T lymphocy...

Direct interaction of proteoglycan macrophage colony-stimulating factor and basic fibroblast growth factor.

The proteoglycan form of macrophage colony-stimulating factor (PG-M-CSF), but not M-CSF with a molecular weight of 85 kD (85-kD M-CSF), bound to immobilized basic fibroblast growth factor (bFGF), and, conversely, bFGF bound to immobilized PG-M-CSF, but not to the 85-kD M-CSF. PG-M-CSF has an additional amino acid sequence at its carboxyl terminus (part of a precursor sequence that is removed in...

Lysophosphatidylcholine regulates synthesis of biglycan and the proteoglycan form of macrophage colony stimulating factor.

OBJECTIVE We have shown that copper-oxidized LDL (Ox-LDL) regulates proteoglycan synthesis by arterial smooth muscle cells. Ox-LDL specifically upregulates biglycan expression while causing elongation of glycosaminoglycan chains on all of the major secreted proteoglycans (biglycan, decorin, and versican), resulting in enhanced lipoprotein-binding interactions. It is not known which component of...
